Abstract
The subclavius posticus muscle is an aberrant muscle with attachments to the first costal cartilage and to the superior angle of the scapula. Although this entity has been identified in cadaveric studies, as far as the authors are aware this is the first report that demonstrates the image of the subclavius posticus muscle in a live patient using magnetic resonance imaging (MRI) and mammography. There have also been no reports of this muscle in radiological literature presenting as a mammographic abnormality. Radiologists and breast surgeons should be aware of this muscle, which can mimic a mass lesion on mammogram. The MRI characteristics of this aberrant muscle are also provided, which can help to differentiate it from a pathological lesion. A band of non-enhancing tissue stretching from the first costal cartilage to the superior angle of scapula, iso-intense to the adjacent muscles in the presence of a normal subclavius muscle are the classical MRI features of the subclavius posticus muscle.
